I get that sometimes people have travel needs and sometimes the car is the only way to go, but last time we had a big snowfall here there were just an absurd number of people trying to drive on unplowed streets with 23 inches of snow. Fortunately there wasn't much ice involved, but people were getting stuck everywhere.
Another tip: if a friendly stranger with a shovel offers to dig your car out when you're stuck, please pay them if you accept their offer. They aren't doing it just to be nice.
